I don't care about a small $10.00 price difference. Honestly, I would have to buy 10 games to make up the difference for just one controller for the PS3...at least Microsoft can say the price of Natal is for 4 players, but then again every game on it is questionable at best, so I am not interested in it.
Could I see Nintendo possibly dropping some prices...maybe, but only because Nintendo's strategy is to not have later price drops and keep retail prices at there starting point. I can see Nintendo dropping prices so that they can later not have to drop prices in the future.
KDR: I do believe you are right. We are half way through this generation of gaming, and Nintendo has already made its money and won the hearts and minds (and dollars) of the consumers and media. So even if Microsoft and Sony are successful with their new controllers, which is doubtful...but still anything is possible...it is unlikely to hurt or effect Nintendo in any significant way. I see late 2011 or early 2012 as Nintendo's year to show off something new in relation to console hardware...and Microsoft and Sony will have only had a year with their new devices out...not enough to change any sort of momentum to do anything to Nintendo...plus Nintendo's own 3DS will most likely push momentum away from Microsoft and Sony and towards Nintendo's future.
